Technical Definition Industrial machine for continuous mechanical extraction of oils from oilseeds and nuts. ## 2. Engineering Reasoning & Causal Matrix > **Operational Intelligence**: Designed for **15-80 bar hydraulic pressure, 0.5-3.0 rpm screw rotation, 60-120°C barrel temperature**. Failure boundary: **Hydraulic pressure >85 bar causes seal extrusion, screw rotation >3.5 rpm induces material bridging, barrel temperature >130°C initiates protein denaturation**, Mechanism: **Seal failure via extrusion at 85 bar due to elastomer yield strength (15 MPa), bridging at 3.5 rpm from insufficient material residence time (τ<45s), thermal degradation at 130°C from protein denaturation kinetics (k=0.12 min⁻¹)**. ### 2.1 Analytical Physics Model Governed by the **Thin-Wall Pressure Vessel Stress Analysis**: > **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$ > **Engineering Impact**: Determines the hoop stress boundary to prevent rupture. | Symbol | Variable Definition | Localized Reference | | :--- | :--- | :--- | | P | Internal Pressure | Engineering Constant | | D | Diameter | Engineering Constant | | t | Wall Thickness | Engineering Constant | ### 2.2 FMEA (Failure Mode & Effects Analysis) | Event Trigger | Severity | Failure Mode | Mitigation Strategy | | :--- | :--- | :--- | :--- | | Hydraulic fluid contamination (ISO 4406 Class >20/18/15) | 8 | Servo valve spool sticking causing pressure oscillations (±10 bar) | Install 3 μm absolute filtration with differential pressure monitoring (ΔP>2 bar alarm) | | Screw-barrel clearance wear exceeding 0.8 mm (initial 0.3 mm) | 8 | Reduced extraction efficiency (oil yield <85% of theoretical) | Hard chrome plating (800 HV) on screw flights with ultrasonic thickness monitoring (1 mm minimum) | ## 3.
